International Criminal Court prosecutors say they are expanding the indictment against a member of fugitive warlord Joseph Kony's feared Lord's Resistance Army to add dozens more charges.

Dominic Ongwen, who has been in the court's custody in The Hague since January, originally faced seven charges linked to a single attack on a refugee camp in Uganda in 2004. Prosecutors announced Thursday they will issue a new indictment Dec. 21 that includes 67 charges which cover attacks on three more camps and overarching charges of persecution, sexual crimes and using child soldiers.

A hearing to judge whether the evidence is strong enough to send Ongwen to trial is scheduled for Jan. 21.

Kony, whose brutal militia has terrorized parts of Uganda and neighboring countries for years, remains at large.
